Calotrichopsis
Calotrichopsis is a small genus of cyanolichens placed in the family Porocyphaceae. The genus was originally circumscribed by the Finnish lichenologist Edvard August Vainio in 1896. A 2024 multilocus study of the class Lichinomycetes emended Porocyphaceae and provisionally included Calotrichopsis in that family; earlier references had kept the genus in Lichinaceae. Species are minute, dark-coloured lichens partnered with cyanobacteria and are typically found on rock or soil in open, intermittently wet microhabitats. The family placement is considered tentative pending additional molecular sampling.
